No spots on quail eggs

[Phunktacular]

I have about 40 jumbo wild coturnix hens. Yesterday I picked up about 30 eggs. About 1/2 of them had no color on them. Just plain tan eggs with no spots. I'm curious what causes this. Would they be any good to try incubating or should I just eat then and collect different eggs to incubate?

The spots are just pigment. There shouldn't be a difference between the eggs. I got a white egg last night myself.

I thought that, too. But, because there were so many, I'm thinking there may be some environmental or diet cause. Nothing has changed in months, though.
